I would like to create the 48v phantom power from my 30v 300w smps. Did a little google searching and I was thinking about trying the MC34063. Can it be done or is there any other suggestions. I am powering 2 mics.

Reason: Additional info

Very few microphones require true 48 volt phantom power. So if for fun you want to make one you actually need 52 volts. Otherwise most any voltage above 12 volts will work. Most microphones convert the voltage to a constant current so all the lower voltage does is create less heat.
